"Great sound reproduction but not durable"2.5 starson by kac8
Pros: Excellent clarity and crisp sound. The snug fit really can block ambient noise well, and the multiple options for eartips ensure good fit.
Cons: Thin wires helped keep these earphones lightweight, but also limited the durability.
Summary: I did a fair amount of research looking for quality earbuds, having had enough of headphones and the restrictions they create in many circumstances. I settled on these Etymotic ER-4P earphones and was entirely satisfied with the great sound quality and the fit. I used them mostly during travel on airplanes, and occasionally for discrete home listening, so overall I would say that at most they got episodic use. Within 6 months, sound for the right earbud began to cut out periodically. Moving the piece generally corrected the problem, but within a year of fairly limited use the right earbud had quit altogether. For the price, I hoped for a lot more durability or structural quality. No complaints about the sound reproduction ... when they worked, they were amazing.
